Android :: Clearing New Mail Icon / Notification Was Lit Up With A Number

I have a MyTouch and a G1. I used to have an Iphone. On my Iphone, when I would get a new mail message it would light up a red number with how many emails there were on the MyTouch and G1 I get a little notification in the status bar at the top of the phone. My question is on the Iphone if the email notification was lit up with a number of emails that I had... and I went into my HOME computer (or any other computer) and read my email the next time the Iphone would go out to check for mail it would find zero there and turn off the notification. But on my MyTouch and G1, if it goes out to check email and there is none (because it was read elsewhere) it does NOT turn that notification off and it always looks like you have mail until you go into your email on the phone and check only to find none. Any way to fix this?
